TECHNICAL FIELD

[0001] The present invention relates to a hygienic paper pack, and moreparticularly, to a hygienic paper pack capable of containinghygienically and cleanly the contents, such as milk, beverages, etc., inthe paper pack (carton pack) made in the shape of hexahedron by using anopening and closing system for preventing a large gap from beinggenerated due to widening of distal ends of opened wing portions in thepaper pack after the paper pack has been already opened, so that thepaper pack can inhibit the contents from being impregnated with smell offoods in a refrigerator.

BACKGROUND ART

[0002] In a conventional paper pack for containing milk, beverages,etc., when the residual contents in the paper pack are stored in arefrigerator or the like after the paper pack is opened so that itscontents are consumed. distal ends of opened wing portions in thepreviously opened paper pack become wider. Thus, it is difficult to sealup the residual contents only by itself, so that the contents are easilyexposed to the environment. Consequently, the contents in the paper packare impregnated with the smell of various foods in the refrigerator andall kinds of bacteria living in the refrigerator may permeate into thecontents. When the residual contents in the opened pack stored in therefrigerator are consumed again. there are various problems in that theresidual contents may go bad and may not be hygienically clean. may beimpregnated with the bad smell of foods. and the like. Therefore someapproaches to the method for sealing up and storing the carton pack havebeen attempted, such as fitting of a pin (or a clip) into the cartonpack. appliance of an adhesive to the carton pack, etc. However. theapproaches have not been put to practical use because it is inconvenientand cumbersome to use them regardless of respective places.

DISCLOSURE OF INVENTION

[0003] Therefore. the present invention has been conceived to solve theabove problems.

[0004] The object of the present invention is to provide a hygienicpaper pack, wherein the paper pack itself seals up opened wing portionsof the paper pack to the utmost by preventing distal ends of the openedwing portions from becoming wider not to generate a gap so that thepaper pack can cleanly, freshly and hygienically contain and store itscontents within the term of distribution, does not cause anyinconvenience and confusion in use and can prevent the contents frombeing gushed from the paper pack when the opened paper pack containingthe contents is turned over inadvertently in its use.

[0005] In order to achieve the above object of the invention, the paperpack according to the present invention employs an easily opening andclosing system by which the paper pack itself can promote the efficiencyof sealing up the opened wing portions thereof to the utmost withoutattaching any separate supplementary materials or objects thereto sothat the paper pack can hygienically and freshly contain and store itscontents and simultaneously the paper pack in which its contents havebeen completely consumed can be recycled in a conventional mannerwithout hindrance.

BEST MODE FOR CARRYING OUT THE INVENTION

[0010] Hereinafter. a preferred embodiment of the present invention willbe explained in detail with reference to the drawings.

[0011] A hygienic paper pack of the present invention shown in FIGS. 1to 4 is a paper pack for containing the contents. such as milk.beverages. etc. The paper pack has a characteristic feature that wingportions adhered to each other at both sides of the paper pack andforming certain portions of an uppermost portion of a paper pack body10. are formed with cutting portions and that the portion between theportions can be folded thereabout.

[0012] Cutting (scored) portions of distal ends of wing portions 30 areformed in the shape of oblique line at both sides of the paper pack fromthe distal ends of wing portions 40, which form the certain portions ofthe uppermost portion of the paper pack body 10, to an upper portion ofa lower end sunken groove 20 therebelow, so that an inverted trapezoidalfolding portion 50 are formed so as to keep the distal ends of wingportions, which will have been opened, in close contact with each other.

[0013] The inverted trapezoidal folding portion 50 constructed by thecutting (scored) portions 30 at both sides of the paper pack can befolded forward or rearward of the paper pack between the upright distalends of wing portions 40 at both sides. so that the opened distal endsof wing portions come into close contact with each other and are lockedfor preventing them from spontaneously becoming wider.

[0014] Next, FIG. 1 is a front view showing the hygienic paper pack of apreferred embodiment according to the present invention. It is shown inthe figure that the folding portion 50 constructed by the cutting(scored) portions 30, which is a portion to be folded when the paperpack containing the contents is stored after being opened, takes theshape of inverted trapezoid, by forming the cutting, (scored) portions30 in the shape of oblique line at both sides of the paper pack from thedistal ends of wing portions 40. which form the certain portions of theuppermost portion of the paper pack body 10. to the upper portion of thelower end sunken groove 20 therebelow.

[0015] The cutting (scored) portions are constructed to have a partiallysevered structure, and thus. they can be easily severed in use.

[0016]FIG. 2 is a perspective view showing the hygienic paper pack ofthe present invention with the folding portion thereof folded. It isshown in the figure that when the folding portion 50 is folded rearwardafter the cutting (scored) portions 30 at both sides of the paper packare severed in order to close the previously opened paper pack again.the folding portion 50 and the cutting (scored) portion 30 form aninverted trapezoid together and simultaneously are folded. By formingthe inverted trapezoidal shape, the cutting (scored) portions 30 serveas latches to be locked at oblique cutting portions of the distal endsof wing portions 40 and thus resist the force that intends to laterallywiden the twofold distal ends of wing portions 40 which had been opened,so that a gap is not generated between the two-fold distal ends of wingportions 40.

[0017]FIG. 3 is a front view showing the hygienic paper pack of thepresent invention with the folding portion thereof folded. It is shownin the figure that the cutting (scored) portions 30 at both sides of thepaper pack are severed and the inverted trapezoidal folding portion isfolded rearward when the contents in the previously opened paper packare stored again.

[0018]FIG. 4 is a side view showing the hygienic paper pack of thepresent invention with the folding portion thereof folded. If theinverted trapezoidal folding portion is laterally (in the figure) foldedafter the cutting (scored) portions 30 are severed. the folded, invertedtrapezoidal folding portion including a central distal end isperpendicular to the upright distal ends of wing portions 40. so thatthe cutting (scored) portions 30 of the inverted trapezoidal foldingportion serve as latches to be locked at oblique cutting portions of thedistal ends of wing portions 40 and thus resist the force that intendsto laterally widen the two-fold distal ends of wing portions 40.Consequently, a gap is not generated between the two-fold distal ends ofwin ( portions 40.

[0019] For example, the present invention is not limited to theembodiment described above. and various modifications and changes to thepresent invention which can be easily made by a person having anordinary skill in the art to which the present invention pertainswithout departing from the spirit and scope of the invention defined bythe appended claims will fall within the scope of the invention.

Industrial Applicability

[0020] As described with reference to the embodiment, according to thepresent invention. by providing the cutting portions in the form ofoblique lines to cut (severe) them from the uppermost portion of thebody of the hexahedron paper pack for containing milk. beverages. etc.to the upper portion of the lower end sunken groove and by easilyfolding the inverted trapezoidal folding portion laterally after thecutting is made along the cutting portions, there is provided thehygienic paper pack in which a gap between the opened distal ends ofwing portions is reduced to the utmost. The hygienic paper pack hassealing advantages that it can not only cleanly, freshly andhygienically contain and store the contents but also seal up the paperpack for preventing the contents from being inadvertently gushedtherefrom. In addition, since the present invention has an excellentadvantage of highly improving the quality of the eating culture andpreservation of health, the present invention is very useful in view ofthe food storage industry.
